  • Patent number: 4170725
    Abstract: A switch construction including opposed contacts positioned on a base and a bridging contactor slidable between different switch positions. The design of the contacts on the base includes an upper section defining a first surface engageable by a tab formed on the sliding contactor. Second surface portions offset relative to the first surface provide engagement with shoulders defined by the sliding contactor. Resilient means press the sliding contactor against this upper section in a fashion such that the shoulders operate to limit the movement of the sliding contactor. The separate engagement of the tab and shoulders provide separate available current paths for the switch.

  • Patent number: 4139746
    Abstract: A slide switch construction including at least two spaced apart contacts positioned on a base with a slider and bridging contactor assembly attached to the base in a manner such that the assembly is movable over the base for changing switch positions. The bridging contactor comprises a strip of resilient material defining an elongated bridging portion with at least one spring arm extending outwardly from the bridging portion. An engaging surface is defined by the slider for engagement with the spring arm to bend the spring arm relative to the bridging portion when the assembly is attached to the base thereby achieving pressing of the bridging portion against the contacts. Hanger means are defined by the contactor and by the slider to serve as means for holding the slider and contactor together when the assembly is separated from the base.
